6 FAQs about [Nanji Island Microgrid System]

What power sources are in the Nanji Island microgrid?

The Nanji Island microgrid contains four types of power sources: wind power, solar power, DE, and energy storage. The lithium batteries have three operating modes: P/Q, constant V/F, and droop control. DEs have P-F and Q-V droop control modes. WTs, PV units, and super capacitors have P/Q operating mode only.

What is the control system for the Nanji Island microgrid?

The control system for the Nanji Island microgrid is based on the IEC61850 standard , which coordinates the three control layers using an MMS protocol for between-layer communication and a GOOSE protocol for within-layer communication.

What is the EMS for the microgrid on Nanji Island?

The EMS for the microgrid on Nanji Island is relatively complex due to the large rated capacity and aggregate load. The load on this island is classified into important load, shiftable load, and adjustable load by the controllability of load.

What is Beiji Island microgrid?

Beiji island microgrid Beiji Island is a natural harbor for the petroleum transportation. It had isolated grids with DE generators for a long time. The newly developed microgrid at Beiji is more dependent on PV generation.

What control architecture does Nanji Island use?

All three island microgrids use a three-layer control architecture that consists of a monitoring and scheduling layer, a coordinated control and protection layer, and a local equipment layer. The control architecture of the microgrid on Nanji Island is the most complex among the three microgrids.

How reliable is Nanji Island power supply?

As for the construction of Nanji Island, a high reliability microgrid technology is demonstrated with a dual-microgrid structure, which can support each other. Although the power supply reliability can reach 99.99%, the cost of construction increases by about 20%. In the control strategy, DE is necessary in the power supply configuration.
